Abstract (en)

The present disclosure discloses a shielded insulating shell (100) and an electronic device. The shielded insulating shell (100) includes a shell body (SB) provided with a first cavity (R1), with an inner shielding layer (IS) near the first cavity (R1) and an outer shielding layer (OS) far away from the first cavity (R1) being formed on the shell body (SB); a first structure (ST1) formed on the first cavity (R1), and formed by assembling to comprise at least a first shielding layer, a first insulating layer, a first air gap layer, a second insulating layer, and a second shielding layer arranged sequentially from an inner side to an outer side of the first cavity (R1); and an assembling gap (AG) formed on the first structure (ST1), which cooperates with the first air gap layer to form a creepage path on the first structure (ST1) that extends from the inner shielding layer (IS) to the outer shielding layer (OS).
